相干胶子辐射的非线性方程

Nonlinear equation for coherent gluon emission

Krzysztof Kutak, Krzysztof Golec-Biernat, Stanislaw Jadach, Maciej Skrzypek

摘要:

受目前在LHC上探索的QCD机制的启发,在那里碰撞和动量转移的总能量都很高,我们研究了高能因子分解的演化方程。为了研究末态部分子饱和等效应,人们不可避免地要研究如何将BK和CCFM演化方程的物理学结合起来。本文得到了BK方程的一种新的排它形式,它给出了CCFM方程的一种可能的非线性推广形式。

英文摘要:

Motivated by the regime of QCD explored nowadays at LHC, where both the total energy of collision and momenta transfers are high, we investigate evolution equations of high energy factorization. In order to study such effects like parton saturation in final states one is inevitably led to investigate how to combine physics of the BK and CCFM evolution equations. In this paper we obtain a new exclusive form of the BK equation which suggests a possible form of the nonlinear extension of the CCFM equation.
